INVALID OR HOISTING BED.

Specification of Letters Patent.

Patented Feb. 4, 1908 Application filed March 21. 1907. Serial No.363.628.

To all whom it may concern:

Be it known that I, John J. (70mins, a citizen oi the United States,residing at Clemo, in the county of Wayne and State of Pennsylvania,have invented certain new and useful ln'iprovements in Invalid orHoisting Beds; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which'it appertains to make and use the same.

This invention relates to an invalid or hospital bed provided with meansfor inserting and removing a bed pan without disturbing the patient.

The object of the invention is to provide a bed with simple andefficient mechanism for inserting and removing a bed pan.

In the accompanying drawings,-Figure 1 represents a side perspectiveview of this improved bed in normal position. Fig. 2

represents a side elevation a sccton of the bed on an enlarged scalelowered in position to permit the insertion or removal of the bed pan;Fig. 3 represents a transverse sectional view with the parts in loweredposition; Fig. 4 represents a bottom plan view of a portion of the bed.Figs. 5 and 6 are detail sectional views of the slide, showing the meansfor attaching the mattress section.

In the embodiment illustrated, the bed stead 1 shown is preferably ofiron and has a head and foot board of ordinary construction. The sidemembers 2 and 3 are made in the ordinary form, of angle-iron and. eachhas a portion cut out preferably at or near the middle thereof andprovided with depending bars or rods as 2 and 2 connected at their lowerends by a bar as 7 and forming a depression or recess 4 which extendstransversely across the bed and in which a central section 6 is mountedto move vertically. Brace-rods as 2 and 2 are connected at one end tothe lower ends of the vertical bars or members as 2 and 2 and at theiropposite ends to the side members 2 and 3 near the head and foot of thebed. Secured at their opposite ends to the bars as 7 at opposite sidesof the recess 4 are two pairs of transversely extending spaced bars 8and 9, between each pair of which is pivoted intermediately of theirends cam arms, as 1.0. The lower ends of each set of these arms, as 10,at opposite sides of the recess are pivoted to operating bars 11 and 12,which are connected at one end by a cross bar 13.

On this cross bar 13.

secured one member of a latch 14, which is adapted to be engaged by theother member secured to the side bar 2 to lock the arms in upright ornormal position for holding the mo able bed section in elevated position with the top thereof in the same plane as the stationary sectionsof the bed. Two spiral springs 15 and 16 are attached at one end to theside bar 2 of the bedstead and. at their other ends to the operatingrods or bars 11 and 1.2 at about the center thereof. The upper ends ofthe arms 10 are of the same height to form a support for a slidingmember 17 to be described. This sliding member 17 is of any desiredconstruction, and. as shown, is formed of three slats, as 18, andconnected by end cross bars 19 and 20, one of which is provided with ahand. grip 21 and with a notch 22 at one side to be engaged. by aspring-pressed latch 23 disposed at one side of the recess 4 on the sidemember 2, and is adapted to lock said slide 17 against movement. Thisslide 17 is designedv to receive a bed pan, (not shown), and mountedthereon. are the mattress supporting sections, any desired number ofwhich may be employed. Two of such sections are shown, one of which, 24,is fixed to the slide 17 and the other, 25, is arranged to slide backand forth thereon to permit the bed pan to be placed. on and removed.from the slide 17 at any desired point between the sections 24 and 25.These sections 24 and. 25 may be of any desired construction andpreferably correspond with the remainder of the bed bottom and areprovided with. means to which the mattress sections 26 and 27 may besecured to hold them securely in place when the section 25 is moved. Asshown, these mattress-securing means comprise headed. studs, as 28,arranged in recesses, as 29, in opposite sides of the sections 24 and25, the mattress being provided. with loops, as 30, which hook overthese studs, as 28.

The central transverse opening in the bedframe in which this mechanismis arranged is of a width sufficient to receive and permit the use of abed pan, but not wide enough to permit the body of the patient to sinkthereinto or be disturbed. when the section. 6 is lowered or raised.

In the operation of this apparatus the bed being in its normal position,as shown in Fig. 1, when it is desired to insert the pan, the member ofthe lock or latch 1.4 carried by the cross bar 13 is released from itscoacting member and the side bar 2 and the bar 13 with its connectedoperating bars 11 and 12, is pushed inward against the tension of thesprings 15 and 16, whereby the cam arms, as 10, are turned downward,carrying with them the slide 17 which rests thereon. and the partssupported on said slide. After the lowering of the section 6 the latch23 is disengaged from the notches in the slide 17 and the mattresssection 25 and the slide 17 is drawn outward at the side of the bed; thesection 25 is slipped outward to form a space between it and the fixedsection 24., and the bed pan is placed on the slide 17, which is thenpushed into position under the patient. To remove the pan the slide 17is again drawn out, the pan removed, the section 25 pushed back intocontact with the section 24-, and the slide run in until the latch 23springs in front of the section 25 and into the notch of the slide 17,and the parts are thus locked against transverse movement. The cross bar13 is then drawn forward, being assisted by the springs attached to theoperating bars, which cause the cam arms, as 10 to move into uprightposition and raise the slide 17 and sections 24 and 25 supported thereoninto normal position with the upper surfaces of the mattress sections 26and 27 in the same horizontal plane as the stationary sections of themattress. The coacting members of the latch 14 then spring intoengagement and the section 6 is locked in its normal position.

I claim as my invention 1. An invalid bed comprising a frame havingoppositely disposed depressions or recesses formed in the side membersthereof, means extending transversely of said bed and connected-with theside walls of said recesses, a series of cam arms pivotally connectedintermediately of their ends to said. means, an operating rod pivotallyconnected with the lower ends of said arms, means for locking said rodvin out-drawn position to hold said cam arms upright, a slide supportedon said cam arms and a sectional mattress support mounted on said slide.

2. An invalid bed comprising a frame having a vertically movablesection, a member arranged transversely of said frame adjacent to saidsection, supporting arms for said. section pivoted intermediately oftheir ends to said transversely arranged. member, means for operatingsaid arms to raise and lower said section and a sliding member arrangedon said section.

An invalid bed comprising a frame having a vertically movable section,supporting arms for said section pivoted intermediately of their ends tosaid frame, means for operating said arms to raise and lower saidsection, a sliding member arranged on said section and a bed-pansupporting member arranged to slide transversely in said verticallymovable section.

41. An invalid bed comprising a frame having a vertically movablesection, supporting arms for said section pivoted intermediately oftheir ends to said frame, means for operating said arms to raise andlower said section, a sliding member arranged on said section, a bed-pansupporting member arranged to slide transversely in said verticallymovable section and. means for locking said slide in closed position.

5. An invalid bed comprising a frame having a vertically movablesection, supporting arms for said section pivoted intermediately oftheir ends to said. frame, means for operating said arms to raiseand'lower said section, a sliding member arranged on said section and aspring pressed latch for engaging said slide to lock it in closed,position.

6. An invalid. bed consisting of a frame having a depression extendingtransversely thereof, a section vertically movable in said depression,transversely extending bars arranged on opposite sides of said.depression, operating means for said section comprising a plurality ofseries of spaced arms pivoted intermediately of their ends to said bars,said. series being spaced to form supports for the opposite sides ofsaid vertically movable section, operating rods pivotally connecting thelower ends of the arms of each of said series, a cross-bar connectingsaid rods, a latch member mounted on said cross-bar and adapted toengage a coacting member on the bed-frame, and a spring connected withone of said operating rods and with the bed frame.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
